        "description": "Dicon, simple DI container injection liblary for Python.\n\n---\n\nDicon is a simple \"DI container injection\" library.\n\n## FAQ\n\n- Q. Is `dicon` a dependency injection library?\n- A. No, it does not support dependency injection.  It supports DI container injection and service (singleton) locator.\n\n## Important points\n\n- Simple to use.\n- Clear what it does on each stage.\n- Small overhead.\n\n## Features\n\n- `@dicon.inject_di_container` class decorator supports nested DI container injection, without modification on type.\n- `dicon.DIContainer` provides class resolver and singleton locating.\n\n### Class resolver, no modification on type\n\n```python\nimport dicon\n\nclass A:\n    pass\n\ndi_container = dicon.DIContainer()\ndi_container.register[A]()\ndi_container.freeze()\n\n# Resolve class.\nclass_A = di_container.resolve[A]\na = class_A()\n# dicon.DIContainer does not modify type of the object.\nassert type(a) is A\n# It only modifies constructor.  (Normally it will be not a problem.)\nassert not (class_A is A)\n```\n\n### Nested DI container injection\n\n```python\n@dicon.inject_di_container('_di_container')\nclass B:\n    _di_container = None # Here we get instance of DIContainer.\n\n    def __init__(self, message):\n        print(message, self._di_container)\n\n@dicon.inject_di_container('_di_container')\nclass C:\n    _di_container = None # Here we get instance of DIContainer.\n\n    def __init__(self):\n        self._b = self._di_container.resolve[B]('B must be have DIContainer:')\n\ndi_container = dicon.DIContainer()\ndi_container.register[B]()\ndi_container.register[C]()\ndi_container.freeze()\n\ndi_container.resolve[C]()\n# will print 'B must be have DIContainer: ...'\n```\n\n### Singleton locating\n\nTBW...\n\n## How it works\n\n1. `@dicon.inject_di_container` modifies `__init__` of given class to make it possible `__init__` can take DIContainer as an argument.\n2. `DIContainer.resolve` ties itself to that argument by `functools.partial`.\n\nThat's all.\n\nFor more details, see [tests](tests).\n\n## Other existing solutions\n\n- Dependency injection\n  - There are lots of DI libraries: for example, [injector](https://github.com/alecthomas/injector), [pinject](https://github.com/google/pinject).\n    - IMHO, DI is too complex for python.\n    - Famous liblaries are too complex and not clear how affect to the program.\n    - It seems no one support nested injection.\n- Service locator\n  - [wired](https://github.com/mmerickel/wired)\n    - I personally felt it is too complex.\n  - [factoryfactory](https://github.com/jammycakes/factoryfactory)\n    - It does not support multiple service locators.\n\nI borrowed design of [MicroResolver](https://github.com/neuecc/MicroResolver) in API.\n\n\n",
